摘　　要：水是重要资源,为生态系统提供服务,产水服务便是其中之一。产水服务对维持供水安全和保护环境有重要作用,而土地利用又驱动产水服务发生变化,因此开展土地利用变化对产水服务影响的研究具有重要意义。通过探究产水服务与土地利用变化的关系,找出合理的土地利用方式提高产水服务能力,以平衡生态与社会发展。故本文以东武仕水库流域为研究区,基于气象、水文、土地利用和土壤等数据构建SWAT模型,分析了2010、2015、2020三期土地利用对产水服务的影响。结果表明:随着研究区耕地、林地和草地面积减小,建设用地、湿地、水域和其他用地面积增加,产水服务呈上升状态。流域上游的产水服务能力高于下游和中游,但流域中游的产水量增加程度大于上游和下游。研究结果能为东武仕水库流域水源供给和土地资源合理规划提供科学依据。Water is an important resource that provides services for ecosystems, and water production services are one of them. Water production services play an important role in maintaining water supply security and protecting the environment, and land use changes drive water production services. Therefore, it is of great significance to carry out research on the impact of land use change on water production services. By exploring the relationship between water production service and land use change, we can find out reasonable land use methods to improve water production service capacity, so as to balance ecological and social development. Therefore, this paper takes the Dongwushi Reservoir Basin as the research area, constructs the SWAT model based on the data of meteorology, hydrology, land use and soil, and analyzes the impact of land use on water production services in 2010, 2015 and 2020. The results showed that with the decrease of cultivated land, forest land and grassland area in the study area, the area of construction land, wetland, water area and other land increased, and the water production service increased. The water production service capacity of the upper reaches of the basin is higher than that of the lower and middle reaches, but the increase of water production in the middle reaches of the basin is greater than that of the upper and lower reaches. The research results can provide a scientific basis for the rational planning of water supply and land resources in the Dongwushi reservoir basin.
